ABSTRACT
Water remains the vital resource to sustain civilization around the world. Unfortunately, it is not evenly distributed over the world by season or location. Some parts of the world are subject to severe drought, thus making water a scarce and precious commodity. Other parts of the world experience significant precipitation that causes floods that result in loss of life and property. In some regions of the world, sustainability of life is threatened by the imbalance between the demands and available supplies of water, food and energy.
